    Only 1.5C error? Try 4-5 degrees for me. :) (At times when the temperature is rapidly increasing or decreasing - eg morning and evening with clear skies)

    Can't speak for the HCF82 but the HR92 doesn't use a discrete bead of any sort, it uses a temperature measurement chip with a built in sensor.

    I'm not sure what you're planning to do with it as a "floor sensor" - do you mean a sensor to measure the water temperature of wet underfloor heating or element temperature of electric under floor...

    Looks good but also looks like a lot of work!

    Lets hope you don't need to do a warranty claim on that HR92 - I think the reseller would not be amused... :D

    66% is definitely the HR92 trying to call for heat.

    Unfortunately the battery contacts are a weak point in the HR92 design - I've had to tighten the contacts on all of mine at some point, some...

    Lots of points buried in there so I have a few questions:

    I assume you have the HR92 set to display measured temperature rather than the set point?

    How are you determining the valve hasn't...

    "solution for the variable target flows"? I hope you don't mean by using an OpenTherm monitor?

    Thanks for the recommendations for Intergas. Not sure if that will be an option with grant funding or whether it will be a "here's what we're offering" situation. Will find out on Friday!

  18. Evohome and OpenTherm boiler recommendations?

    Hi All,

    I know the information on which boilers do and don't play well with Evohome OpenTherm is buried in this forum somewhere, and I've read quite a bit of it in the past (and forgotten more...

    A flashing red light on the BDR91 means it is either not bound or has lost comms with the Controller.

    I would fix this first before worrying about reliability of the CS92A, clear the bindings on...

    Yes, the CS92A sends its updates too rarely (1 hour between updates if no changes have occurred) and does not send every message twice like the DTS92 does. It doesn't take many lost messages before...
